The vulnerability of the dns.Msg.Unpack() function in the plugin/pkg/doh/doh.go, core/dnsserver/server_quic.go, and core/dnsserver/server_grpc.go files of the coredns server allows a attacker to compromise the integrity of the protected information.

The vulnerability of the dns.Msg.Unpack function in the plugin/pkg/doh/doh.go, core/dnsserver/serverquic.go, and core/dnsserver/servergrpc.go files of the coredns server is related to the ability to bypass access control mechanisms. Exploiting this vulnerability allows a malicious actor to...

GHSA-9GM5-9RFH-M6VX CoreDNS DoH/DoQ/gRPC bypass UPDATE rejection enforced on UDP/TCP

Summary CoreDNS accepted RFC 2136 UPDATE messages over DoH, DoH3, DoQ, and DNS-over-gRPC, then allowed the proxy/forward plugin to send them unchanged to an upstream DNS server. UDP, TCP, and DoT rejected the same opcode before plugin dispatch. If an update-capable upstream trusts CoreDNS's sourc...

unbound: Unbound: Denial of Service via use-after-free in DoH stream cleanup

A use-after-free vulnerability in Unbound's DNS-over-HTTPS DoH stream cleanup code allows a remote attacker to cause a denial of service DoS. When DoH support is compiled, sending a specially crafted DoH connection under specific failure conditions—such as an RPZ drop query or heavy traffic—cause...

Unity Linux 20.1050e / 20.1060e / 20.1070e Security Update: coredns (UTSA-2026-109796)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-109796 advisory. CoreDNS is a DNS server written in Go. In versions prior to 1.14.3, the gRPC, QUIC, DoH, and DoH3 transport implementations incorrectly handle TSIG authentication. F...

CVE-2026-86003

CoreDNS (a DNS server written in Go) prior to 1.14.7 fails to enforce the dns.DefaultMsgAcceptFunc request policy on its DNS-over-HTTPS, DNS-over-HTTP/3, DNS-over-QUIC, and DNS-over-gRPC listeners. Unlike the UDP, TCP, and DNS-over-TLS paths, these listeners call dns.Msg.Unpack without that polic...

CVE-2026-77692

CVE-2026-77692 allows an unauthenticated remote attacker to crash the BIND 9 named daemon by sending a single crafted DNS-over-HTTPS (DoH) request containing a cryptographically invalid SIG(0) record and then closing the transport connection prematurely . The resulting abort produces an availabil...

CVE-2026-77692 Unauthenticated remote crash of named via a single DoH SIG(0) request

An attacker can cause named to abort by sending a crafted DNS-over-HTTPS request with a cryptographically invalid SIG0 record, and then closing the transport connection prematurely. This issue affects BIND 9 versions 9.20.0 through 9.20.27, 9.21.0 through 9.21.25, and 9.20.9-S1 through 9.20.27-S1...
